Problems solved by technology

[0003] However, in the above-mentioned drying device, since the heated air sprayed to the conveying path is mixed and circulated with the air in the drying device, especially when the volume in the drying device is large, the temperature of the circulating air The drop rate will be large, the time required to heat up is very long, and the thermal efficiency is very bad
In addition, when the concentration measuring device is arranged adjacent to the drying device, there may be a case where the concentration measuring device is affected by the heat from the drying device and cannot accurately measure the density formed on the medium. The density of the image

Abstract

The invention discloses a drying apparatus. The drying apparatus (60) comprises a conveying portion (61) conveying printing paper (2) inside a housing (73), a partition board with holes (74) of a conveying path carrying out conveying spraying heated air to the conveying portion (61), and a circulating mechanism (75) circulating the air sprayed from the partition board with holes (74) facing the partition board with holes (74) through a heating chamber (78) and the air (WB) sprayed to the conveying path without facing the partition board with holes (74). One side opposite to the partition board with holes (74) inside the housing (73) from the conveying path is provided with a partition component (79) having horizontal wall portion (79a). The horizontal wall portion (79a) is configured to between a four-level hole (74a) at the lower part corresponding to the partition board with holes (74) and a three-level hole (74a) at the upper part. Therefore, a drying portion (60) (drying apparatus) with very good thermal efficiency can be obtained.

Description

technical field [0001] The present invention relates to a drying device for drying media in a photo processing device and the like. Background technique [0002] In the photo processing apparatus, media such as film or photographic paper are conveyed while processing such as developing, fixing, or washing, and then the media is conveyed to a drying device disposed on the downstream side of the photo processing apparatus in the conveying direction. In this drying device, the medium subjected to processing such as development is conveyed along the conveying path of the conveying unit, is blown with hot air to dry, and is then discharged onto a conveyor. Under the situation that the density of the image that has been formed on the medium is measured, the medium after drying in the drying device is sent to the density measuring device (for example, referring to Japanese laid-open patent publication) that is arranged on the position adjacent to the drying device Japanese Patent ...
