Claims

[Scope of utility model registration request]

A printing device for a printer having a print head and a head receiving member against which the print head is pressed while holding the print sheet between the print head and the print head. A head support member that swings between a state pressed against the member and a state separated from the member, and a latch rod installed laterally at a rearward extension of the pivot point of the head support member to the fixed frame. and is pivotably supported by the fixed frame and has an engagement groove that engages with the latch rod, so that the print head is pressed against the head receiving member via the head support member by the engagement. It is installed between the operating lever to be held and the extension of the head support member, and when the latch rod and the engagement groove are engaged, the operating lever is biased in the engagement direction, and the lever is A printing device for a printer, comprising a spring that swings a head supporting member so that the printing head separates from the head receiving member when the latch rod is disengaged from the engagement groove by the operation.
