Abstract

The delivery system has a supply device having a supply port for supplying an article; a receiving device having a receiving port that is able to receive the article that is supplied from the supply port; and a detection unit that is capable of detecting: a first state in which the supply device and the receiving device are joined by the supply port engaging with the receiving port; a second state in which the supply device and the receiving device are close together and there is a space between the supply port and the receiving port; and a third state in which the supply device and the receiving device are separated and the space between the device is wider than in the second state.

First claim

What is claimed is:

1. A delivery system comprising:
a supply device having a supply port for supplying an article;
a receiving device having a receiving port configured to receive the article supplied from the supply port; and
a detection unit configured to detect:
a first state in which the supply device and the receiving device are joined by the supply port engaging with the receiving port;
a second state in which the supply device and the receiving device are close together and there is a space between the supply port and the receiving port; and
a third state in which the supply device and the receiving device are separated and a space between the devices is wider than in the second state.

2. The delivery system according to claim 1 , wherein
in the second state and the third state, part of a foot of the receiving device rides up on part of a foot of the supply device, and
the detection unit includes a first sensor that is provided on the foot of the receiving device and detects a positional relationship with the foot of the supply device, and a second sensor that is provided on the foot of the supply device and detects a positional relationship with the foot of the receiving device; and detects a state from output from the first sensor and the second sensor.

3. The delivery system according to claim 2 , wherein
in the first state, detection signals are outputted from the first sensor and the second sensor,
in the second state, the detection signal is not outputted from the first sensor, and the detection signal is outputted from the second sensor, and
in the third state, no detection signal is outputted from either the first sensor or the second sensor.

4. The delivery system according to claim 3 , wherein
the detection unit is further configured to detect a fourth state in which a positional relationship between the supply device and the receiving device is unclear, and
in the fourth state, the detection signal is outputted from the first sensor and the detection signal is not outputted from the second sensor.

5. The delivery system according to claim 1 , further comprising a controller that controls the supply device so that an article is supplied from the supply port in the first state or in the third state.

6. The delivery system according to claim 5 , wherein
the controller controls the supply device so that when an article is supplied from the supply port when in the first state, the receiving device is in a state capable of receiving an article.

7. The delivery system according to claim 1 , wherein
the supply device is a printer that prints an image on a sheet as the article, and
the receiving device is a stacker that stacks a printed sheet.

8. The delivery system according to claim 7 , further comprising
a storage unit that is arranged in a space between the supply device and the receiving device, and stores a sheet supplied from the supply port, the sheet dropping without passing through the receiving device.

9. The delivery system according to claim 8 , wherein
the receiving device is equipped with a stacking unit in which sheets are stacked, and
in the first state sheets supplied from the supply port pass through the receiving port and are stacked in the stacking unit, and in the third state, sheets supplied from the supply port drop into the storage unit without passing through the receiving port.

10. The delivery system according to claim 9 , wherein
the storage unit is equipped with a basket that is formed using a flexible belt-shaped member, with one end of the belt-shaped member being attached to the receiving device, and the other end being attached to the supply device.

11. The delivery system according to claim 1 , wherein
the supply device and the receiving device are electrically connected by a cable connection, and the cable connection is maintained in any of the first state, the second state, and the third state.

12. A delivery system comprising:
a supply device having a supply port for supplying an article;
a receiving device having a receiving port configured to receive the article that is supplied from the supply port; and
a storage unit that is arranged between the supply device and the receiving device and stores sheets that are supplied from the supply port, wherein
the system is configured to have a first state in which the supply port and the receiving port engage and the supply device and the receiving device are joined, and to have a second state in which the supply device and the receiving device are separated, and
in the first state, sheets that are supplied from the supply port are delivered by way of the receiving port, and in the second state, sheets drop into and are stored in the storage unit without passing through the receiving port.

13. The delivery system according to claim 12 , wherein
the storage unit is equipped with a basket that is formed using a flexible belt-shaped member, with one end of the belt-shaped member being attach to the receiving device, and the other end being attached to the supply device.

14. A delivery system comprising:
a supply device having a supply port for supplying an article; and
a receiving device having a receiving port configured to receive the article that is supplied from the supply port, wherein
the system is configured to have a first state in which the supply port and the receiving port engage and the supply device and the receiving device are joined, and to have a second state in which the supply device and the receiving device are separated, and
the supply device and the receiving device are electrically connected by a cable connection, with the cable connection being maintained in both the first state and the second state, and electric power is supplied by way of the cable connection from the supply device to the receiving device, or from the receiving device to the supply device.
