(1)に記載のプリンタ。[Scope of Claim for Utility Model Registration] (1) A printer equipped with a printing mechanism that uses the movement of the carriage to drive the print head and an automatic gap adjustment mechanism that adjusts the gap between the print head and the paper according to the thickness of the paper. In, a part of the shaft that pivotally supports the carriage,
A lever cam that interlocks with this shaft and a switching lever that semi-interlocks with this lever cam are provided, and until the switching lever is set to the maximum gear position, the lever cam and the shaft are interlocked by operating the switching lever, so that manual gearing is not possible. What is claimed is: 1. A printer according to claim 1, wherein the automatic gap adjustment mechanism is configured to be adjustable and to operate when the switching lever is set to the maximum gap position. (2) In order to interlock the lever cam with the shaft and to bring the lever cam into close contact with the switching lever when the switching lever is at the maximum gap position,
A claim characterized in that a counterclockwise pressing force is applied to the lever cam by a spring.
The printer described in (1).
