Claims

[Scope of utility model registration request]

(1) Detecting the remaining amount of transfer paper on the supporting member of a paper feeding means configured such that the supporting member that holds the transfer paper moves in the direction of the paper feeding position according to the remaining amount of transfer paper. In the transfer paper remaining amount detection device, a light emitting section and a light receiving section are provided, and reflected light to the light receiving section changes depending on the position of the supporting member.
1. A transfer paper remaining amount detection device, wherein a signal indicating the remaining amount of transfer paper is output based on the amount of transfer paper remaining. 2. The transfer paper remaining amount detection device according to claim 1, wherein the support member that supports the transfer paper is provided with a transfer paper remaining amount level marker that reflects light from a light emitting section. 3. The transfer paper remaining amount detection device according to claim 2 of the utility model registration claim, wherein the transfer paper remaining amount level marker is attached to a support member that supports the transfer paper so as to be adjustable in one position.
