<p>PURPOSE:To realize a rotary tray drive mechanism not allowing the engagement between the tooth part of the rotary tray and the tooth part of a driving gear to be misaligned to caused malfunction even when environment temperature changes in the construction of the rotary tray which is a resin moulding and a mechanical chassis which is a sheet metal, in a rotary tray drive mechanism. CONSTITUTION:The rotation of a rotary tray 1 is performed by providing the rotary tray 1 with a drive gear 9 and a tooth part 1c corresponding to it which rotate in a direction perpendicular to the main face of the rotary tray 1 and which are arranged in the tangent direction of the rotary tray 1. In the construction as shown above, the rotary tray made of resin mould and the mechanical chassis made of sheet metal, for example, even when the environment temperature changes, the engagement between the tooth part of the rotary tray and that of the drive gear is not misaligned because the engagement is made in the vertical direction, and thus, the rotary tray drive mechanism not causing the malfunction can be reaslied.</p> |
