PURPOSE:To display counter interlocking with recording apparatus with a simple constitution by providing a cassette with an electrochromic display for counter display and input contacts for an electric signal driving the display. CONSTITUTION:The electrochromic display (ECD) for counter display is provided with the input contact 103g inputting electric signals driving the ECD and a display part and upper and lower electrodes 103d, 103b, etc. are laminated on a substrate 103a. Two ECDs 103 are prepared and adhered turning the edge of a cassette housing 101 so as to be reversed each other. The cassette 1 having said constitution is set to a camera and the driving device is engaged with a hub 102a and contacted with a disc 102. Therefore, a signal to be counted is displayed on the display part of the ECD103 through the contact 103g as a colored numeral and observed through the window of a camera case. Even if the cassette is replaced on the way of display, the display is kept as it is by the storage characteristics of the ECD. |
