Abstract
PURPOSE:To make a detection means with low detecting sensitivity possible to be used by detecting the time when a head carriage reaches a prescribed moving position, a member to be detected rotated by a stepping motor reaches a prescribed rotating position and the exciting phase of the stepping motor at this time coincides with an exciting phase previously set as a reference position. CONSTITUTION:A supporting member 60 is provided with the lower part of a main frame 30 and a rotating shaft 62 and a photointerrupter 64 are provided with this member 60. Then a gear 66 and a slit board 68 are inserted in the rotating shaft 62 and the gear 66 and a gear 35 are meshed with each other. The photointerrupter 64 outputs the detection signal of a slit 68A when the slit 68A formed on the slit board 68 reaches the position shown by a figure and a covered state between a light emissing part 64A and a light receiving part 64B is opened. On the other hand, a sub-switch 69 having a detection element 69A is provided on the main frame 30 and this switch 69 outputs the detection signal of the head carriage when the head carriage 40 moves to the prescribed position and the detection element 69A is pressed by the head carriage 40.
