A thermal transfer light pen and a thermal transfer apparatus favorably perform thermal transfer even using light as a heat source to a thermal transfer sheet and performing thermal transfer to a transfer object with an uneven surface. A thermal transfer light pen includes a hollow pen body including a front end portion, a pressing body in the front end portion of the pen body and including a curved surface projecting toward a front end, a light guide including a first end and a second end, at least a portion of the light guide inside the pen body, and a light source connected to the first end of the light guide. The second end of the light guide is disposed in the front end portion of the pen body and faces the pressing body in the pen body. The pressing body is made of a material transparent to light emitted from the light source.

Thermal transfer light pen and thermal transfer apparatus

A diaphragm pump includes a pump chamber, a diaphragm, and a diaphragm deformer. The pump chamber is box-shaped and includes at least an inlet opening, an outlet opening, and a diaphragm attaching opening. The pump chamber is provided with an inner space. A diaphragm is made of an elastically deformable material, and is provided in the pump chamber so as to cover the diaphragm attaching opening. The diaphragm deformer elastically deforms the diaphragm to change a capacity of the inner space. The outlet opening is located at a highest position in the inner space of the pump chamber.

A diaphragm pump includes an inflow chamber and an outflow chamber. The inflow chamber is provided with an inflow valve seat. An inflow valve that prevents backflow of a liquid is disposed against the inflow valve seat. The outflow chamber is provided with an outflow valve seat. An outflow valve that prevents backflow of a liquid is disposed against the outflow valve seat. The diaphragm pump also includes an inflow-valve presser that presses the inflow valve against the inflow valve seat, and an outflow-valve presser that presses the outflow valve against the outflow valve seat. Each of the inflow valve and the outflow valve is defined by an elastically deformable member. Each of the inflow valve seat and the outflow valve seat includes a surface at least a portion of which is a curved surface.
