Sheet transfer apparatus
First Claim
1. A sheet transfer apparatus comprising:
- a sheet receiver for receiving a sheet, the sheet receiver including an openable member which is movable between an open position and a closed position;
a transfer mechanism for transferring the sheet from the sheet receiver along a predetermined transfer path;
a common detecting device provided at a predetermined position in the transfer path for detecting a transfer state of the transferred sheet and for detecting an open/closed state of the openable member; and
a controller for determining whether the detecting device is detecting the transfer state of the transferred sheet or the open/closed state of the openable member.

Abstract
A sheet transfer apparatus includes a sheet receiver for receiving a plurality of sheets, and a transfer mechanism for successively transferring each of the sheets from the sheet receiver along a predetermined transfer path. The sheet receiver has an openable member which is movable between an open position and a closed position. The sheet transfer apparatus further includes a detecting device provided at a predetermined position in the transfer path for detecting a transfer state of each transferred sheet and for detecting an open/closed state of the openable member, and a controller for determining whether the detecting device is detecting the transfer state of each transferred sheet or the open/closed state of the openable member.

8. A sheet transfer apparatus comprising:
-
a sheet receiver for receiving a sheet, the sheet receiver including an openable member which is movable between an open position and a closed position; a transfer mechanism for transferring the sheet from the sheet receiver along a predetermined transfer path, the transfer mechanism including a platen roller provided at an intermediate position of the transfer path; a first detecting device provided in the transfer path upstream from the platen roller for detecting a transfer state of the transferred sheet, the first detecting device being connected to the openable member for detecting an open/closed state of the openable member; a second detecting device provided in the transfer path downstream from the platen roller for detecting a transfer state of the transferred sheet; and a controller for detecting an abnormality on the basis of detection signals from the first and second detecting devices and a drive state of the transfer mechanism, the controller prohibiting the transfer mechanism from operating upon detection of the abnormality, the controller further allowing the transfer mechanism to operate upon closing the openable member after removal of a cause for the abnormality. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
