Abstract

In a cutting device, a cutting blade is reciprocally movable within a movable range including a first retracted position away from a target to be cut and a cut complete position at which cutting of the target is to be completed. A memory is configured to store cutting data indicating the first retracted position. A controller is configured to perform controlling, in response to determining that the cutting blade has stopped at an intervening position between a cut start position at which cutting of the target is started and the cut complete position, a drive portion to move the cutting blade from the intervening position to a second retracted position positioned within the movable range and away from the target. The controller is configured to further perform updating the cutting data stored in the memory so as to indicate the second retracted position in place of the first retracted position.

First claim

What is claimed is:

1. A cutting device comprising;
a cutting blade reciprocally movable within a movable range including a first retracted position away from a target to be cut and a cut complete position at which cutting of the target is to be completed;
a drive portion configured to move the cutting blade;
a memory configured to store cutting data indicating at least the first retracted position; and
a controller configured to perform:
(a) controlling the drive portion to move the cutting blade from the first retracted position to the cut complete position according to the cutting data, thereby cutting the target;
(b) controlling the drive portion to move the cutting blade from the cut complete position after the (a) controlling is completed;
(c) controlling, in response to determining that the cutting blade has stopped at an intervening position during one of the (a) controlling and the (b) controlling, the drive portion to move the cutting blade from the intervening position to a second retracted position, the intervening position being in between a cut start position at which cutting of the target is started and the cut complete position, the second retracted position being positioned within the movable range and being away from the target; and
(d) updating the cutting data stored in the memory so as to indicate the second retracted position in place of the first retracted position.

2. The cutting device according to claim 1 , wherein the controller is configured to further perform:
(e) receiving a command instructing to move the cutting blade to the second retracted position, and
wherein the (c) controlling is performed in response to receiving the command.

3. The cutting device according to claim 2 , further comprising:
an input interface configured to receive a user operation, the command being received via the input interface.

4. The cutting device according to claim 3 , wherein the cutting device is accommodated in a housing of a printing device, the housing being formed with a discharge opening through which the target is discharged, and
wherein the input interface is provided near the discharge opening.

5. The cutting device according to claim 1 , further comprising:
a sensor configured to detect the cutting blade being positioned in the first retracted position,
wherein the (c) controlling is performed in a case where the sensor fails to detect the cutting blade being positioned in the first retracted position.

6. The cutting device according to claim 5 , wherein the controller is configured to further perform:
(f) acquiring a shift amount between the intervening position and the second retracted position, and
wherein the (c) controlling controls the drive portion to move the cutting blade by a distance corresponding to the shift amount from the intervening position.

7. The cutting device according to claim 5 , wherein the controller is configured to further perform:
(g) measuring an operating time required for the (a) controlling and the (b) controlling, and
wherein the (c) controlling is performed in a case where the operating time reaches a prescribed time without detecting the cutting blade being positioned in the first retracted position.

8. The cutting device according to claim 1 , wherein the (b) controlling decelerates the cutting blade before the cutting blade reaches the first retracted position during movement from the cut complete position to the first retracted position and stops the cutting blade at the first retracted position.

9. The cutting device according to claim 1 , wherein the controller is configured to further perform:
(h) detecting an overload on the drive portion during one of the (a) controlling and the (b) controlling; and
(i) halting the one of the (a) controlling and the (b) controlling in response to detecting the overload.

10. A printing device comprising:
a printing portion configured to perform a print on a target; and
a cutting device comprising:
a cutting blade reciprocally movable within a movable range including a first retracted position away from the target to be cut and a cut complete position at which cutting of the target is to be completed;
a drive portion configured to move the cutting blade;
a memory configured to store cutting data indicating at least the first retracted position; and
a controller configured to perform:
(a) controlling the drive portion to move the cutting blade from the first retracted position to the cut complete position according to the cutting data, thereby cutting the target;
(b) controlling the drive portion to move the cutting blade from the cut complete position after the (a) controlling is completed;
(c) controlling, in response to determining that the cutting blade has stopped at an intervening position during one of the (a) controlling and the (b) controlling, the drive portion to move the cutting blade from the intervening position to a second retracted position, the intervening position being in between a cut start position at which cutting of the target is started and the cut complete position, the second retracted position being positioned within the movable range and being away from the target; and
(d) updating the cutting data stored in the memory so as to indicate the second retracted position in place of the first retracted position.

11. The printing device according to claim 10 , wherein the cutting device is operable in a non-cutting mode in which cutting of the target is suspended.

12. The printing device according to claim 10 , wherein the controller is configured to further perform:
(e) receiving a command instructing to move the cutting blade to the second retracted position, and.
wherein the (c) controlling is performed in response to receiving the command.

13. The printing device according to claim 12 , wherein the cutting device further comprises an input interface configured to receive a user operation, the command being received via the input interface.

14. The printing device according to claim 13 , further comprising:
a housing formed with a discharge opening through Which the target is discharged,
wherein the input interface is provided near the discharge opening.

15. The printing device according to claim 10 , wherein the cutting device further comprises a sensor configured to detect the cutting blade being positioned in the first retracted position, and
wherein the (c) controlling is performed, in a case where the sensor fails to detect the cutting blade being positioned in the first retracted position.

16. The printing device according to claim 15 , wherein the controller is configured to further perform:
(f) acquiring a shift amount between the intervening position and. the second retracted position, and
wherein the (c) controlling controls the drive portion to move the cutting blade by a distance corresponding to the shift amount from the intervening position.

17. The printing device according to claim 15 , wherein the controller is configured to further perform:
(g) measuring an operating time required for the (a) controlling and the (b) controlling, and
wherein the (c) controlling is performed in a case where the operating time reaches a prescribed time without detecting the cutting blade being positioned in the first retracted. position.

18. The printing device according to claim 10 , wherein the (b) controlling decelerates the cutting blade before the cutting blade reaches the first retracted position during movement from the cut complete position to the first retracted pos
